Evening Black Shoe.
How right you are re the Engineers.
I well remember on my first ship back in 1972 RFA (Royal Fleet Auxiliary) Retainer.
She was by all standards an old girl by then and although powered if I remember correctly with a Doxford Engine on a single screw if we ran up to full speed (max 15 knots)Just made a nice ripple on the bow,but not enough to water ski off the stern.
She would throw out enough smoke to cover an entire convoy if we were at war.
The exhaust soot and detritus that blew out of our funnel was unbelievable.You would think we were burning coal 😂😂
Good days,long gone.
